What is 317L Stainless Steel Spectacle Blind?

Stainless Steel 317L spectacle blind consists of a blind and spacer. The blind is installed in between flanges to securely shutdown pipeline during leakage or maintenance. When a 317L Stainless Steel blind is not required, a spacer can be installed in between flanges to continue regular operating conditions.

A Stainless Steel 317L Spectacle Blind is a method of connecting pipes, valves, pumps and other equipment to form a piping system in Petro and chemical industry. 317L Stainless Steel Spectacle Blind also provides easy access for cleaning, inspection or modification. SS 317L Spectacle Blind are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. All types except the A182 Stainless Steel 317L Spectacle Blind are provided with a raised flange face. Each ASME SA182 F317L Spectacle Blind according to ASME B16.5 has a number of standard dimensions.

What are PN10, PN16 and PN25 Standards Spectacle Blind

PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric Spectacle Blind dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements. Spectacle Blind produced to ANSI, AWWA, ASA, or old British standards that are dimensioned in inches will not mate up with metric flanges in general. It is good practice when specifying a PN flange standard to indicate the actual working pressure since it is a common occurrence that a specific PN, say PN16, flange drilling is required on a fitting or valve to match adjacent flanges, but the pressure requirement is less than PN16.

  • Table E
  • Table F
  • Table G
  • Table H
  • Table J
  • Table K

  • Table D
  • Table E
  • Table F
  • Table G

ANSI Spectacle Blind

  • ANSI 125
  • ANSI 150
  • ANSI 300
  • ANSI 600
  • ANSI 900
  • ANSI 1500

 

  • Higher numbers denote higher pressures.
  • Sometimes people use the word ‘Class’ instead of ANSI. e.g. an ANSI 150 Spectacle Blind might be called a ‘Class 150’
  • All dimensions are specified in inches.

SUS 317L Spectacle Blind Heat Resistance

Significantly better corrosion resistance that T-316 in the same environments. Good oxidation resistance in continuous service to 925°C and in intermittent service to 879°C.

AISI 317L Spectacle Blind Heat Treatment

AISI 317L stainless steel Spectacle Blind is non-magnetic in the annealed condition and is non-hardenable by heat treatment. Machinability is 39% – 65 surface feet per minute.

SS 317L Spectacle Blind Fabrication

Alloy 317L stainless steel Spectacle Blind can be easily welded and processed by standard shop fabrication practices.

317L Stainless Steel Spectacle Blind producing through Cold forming

Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.

Stainless Steel 317L Spectacle Blind Machining

Low speeds and constant feeds will minimize this alloy’s tendency to work harden. Tougher than 304 stainless steel Spectacle Blind with a long stringy chip, the use of chip breakers is recommended.

317L Spectacle Blind Welding

317L stainless steel Spectacle Blind can be readily welded by most standard processes. A post weld heat treatment is not necessary. 317L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317L should be used to weld 317L steel.

Alloy 317L Spectacle Blind Hot Forming

317L stainless steel Spectacle Blind are non-magnetic in the annealed condition and is non-hardenable by heat treatment. Machinability is 39% – 65 surface feet per minute.

MSS, API, AWWA, ANSI AND CSA STANDARDS

ANSI, MSS and API standards govern flange dimensions and tolerances. ASME/ANSI B16.5, titled “ Steel Pipe Flanges and Flanged Fittings”, is the basic standard. It covers forged steel flanges, sizes NPS 1/2 (DN 15) through NPS 24 (DN 600). CSA standard CAN3-Z245 12-M96 covers the manufacture, dimensions, tolerances and material requirements for pipe line flanges. ASME/ANSI B16.36 covers Orifice flanges. The following MSS, API and AWWA standards are written to supplement B16.5:

  • MSS SP-6: Flange facings
  • MSS SP-9: Spot facing for bronze, iron and steel flanges
  • MSS SP-25: Marking of flanges
  • MSS SP-39: Bolts and nuts for flanges
  • API6A: Wellhead equipment
  • AWWA C207: Hub flanges

The following codes are not flange specifications, but they influences the manufacture of forged steel flanges:

  • ASME: Boiler and Pressure Vessel Code
  • ASME/ANSI B31.1: Power Piping
  • ASME/ANSI B31.3: Petroleum and refinery piping
  • ASME/ANSI B31.4: Liquid petroleum transportation piping systems
